Title: Werner Diemi: Innovator in Beverage Can Technology
Introduction
Werner Diemi is a notable inventor based in Bern, Switzerland. He has made significant contributions to the field of packaging technology, particularly in the design of beverage can lids. With a total of 2 patents to his name, Diemi's innovations have improved the functionality and efficiency of can manufacturing.
Latest Patents
One of Diemi's latest patents is the grooved beverage can lid. This innovative design features a pre-fabricated pouring outlet that is positioned at an angle of either 0 degrees or 90 degrees to the rolling direction of the sheet from which the lid is made. The lid incorporates at least one ring-shaped stiffening groove that points towards the can interior. This groove is concentric with the periphery of the lid and is interrupted in the region of the pouring outlet. The diameter of the groove is designed to be 65-80% of the nominal diameter of the can. This stiffening groove enhances the lid's resistance to internal pressure by approximately 10%, allowing for a reduction in lid thickness while maintaining material integrity.
Another significant patent by Diemi is a method for producing aerosol can tops. This method involves two operations on a transfer press. The first operation creates a score line on the upper radius of the pre-drawn cylindrical portion, compressing the material for a clean and burr-free separation. In the subsequent operation, the disc is radially pulled towards the center, formed into a cup, and ejected downwards. This process ensures that the edge of the opening is clean, smooth, and free of burrs, facilitating the formation of the curl without the risk of splitting when using harder and less expensive materials.
